CHAPTER 10 REAL-TIME OUTPUT FUNCTION
10.2 Control Register
(1) Buffer register (PB)
The buffer register is a register to which the data to be output from the real-time output port is written
beforehand.
This register can be read/written in 8- or 1-bit units.
(2) Output latch (RTP)
The output latch is a register to which the data of the PB register is transferred by the coincidence signal with
the CM10 register. Write the value to be output to external to the RTP register before setting the port as a
real-time output port with the PMC13 register.
This register can be read/written in 8- or 1-bit units.
10.3 Operation
When the corresponding bit is set to the control mode by the PMC13 register, the output pins can be used as a
real-time output port. These pins can be accessed by the PB register and the RTP register.
The data is output by the following procedure.
<1> The data is written to the PB register.
<2> The contents of the PB register is transferred to the RTP register at the generation timing of the compare
coincidence interrupt of timer (INTCM10).
<3> The contents of the RTP register is output to the pins set as the real time output port.
